- The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.

- Your blood is pumped around by the heart which is the main function in your circulatory system. The heart sends blood through your blood vessels. The circulatory system consists of the heart, blood vessels, lymph, blood, and the lymphatic vessels and glands.

Vein (June 2012). In the circulatory system, veins (from the Latin vena) are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart.In contrast to veins, arteries carry blood away from the heart.owever, in pulmonary circulation, the arteries carry deoxygenated blood from the heart to the lungs, and veins return blood from the lungs to the heart. The difference between veins and arteries is their direction of flow (out of the heart by arteries, returning to the heart for veins), not their oxygen content.

The Heart and Blood Vessels Veins are the blood vessels that carry blood back to the heart. They may contain valves which stop blood flowing away from the heart. The heart works by following a sequence of electrical signals that cause the muscles in each chamber to contract in a certain order. blood vessel's main function is to transport blood around the body. Blood vessels also play a role in controlling your blood pressure. Blood vessels are found throughout the body. There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins.

Diagram of the Human Circulatory System (Infographic) The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.he system of blood vessels in the human body measure about 60,000 miles (96,560 kilometers). Arteries carry oxygen-rich blood from the heart through the body. Veins carry oxygen-poor blood back to the heart. The superior vena cava carries oxygen-poor blood into the heart.

Heart Function: The cardiac veins returns deoxygenated blood (containing metabolic waste products) from the myocardium to the right atrium. This blood then flows back to the lungs for reoxygenation and removal of carbon dioxide.

THE CIRCULATORY SYSTEM Veins are blood vessels that transport blood to the heart. With the exception of the pulmonary vein, they carry deoxygenated blood. They have three layers in their walls as well. The main difference is that there is less smooth muscle in the middle layer and less connective tissue in the outer layer.escribe the 4 functions of the cardiovascular system. 1. Contractions of the heart generate blood pressure which moves blood through the blood vessels. 2. Blood vessels transport blood from the heart to the arteries, capillaries, and veins. Blood then returns to the heart. 3. Gas exchange occurs in the capillaries.

Cardiovascular System Function Blood circulates through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. The heart pumps the blood around the blood vessels. Functions of blood and circulation: 1  Circulates OXYGEN and removes Carbon Dioxide. 2  Provides cells with NUTRIENTS. 3  Removes the waste products of metabolism to the excretory organs for disposal. 4  Protects the body against disease and infection.

How Veins Transport Blood Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins. 1  Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. 2  Systemic veins return oxygen-depleted blood from the rest of the body to the right atrium of the heart.

- Overview. The cardiovascular system consists of the heart, which is an anatomical pump, with its intricate conduits (arteries, veins, and capillaries) that traverse the whole human body carrying blood. vein is a blood vessel that has a larger lumen, and sometimes veins serve as blood reservoirs or capacitance vessels, containing valves that prevent backflow. This system of vessels in general returns blood to the heart from the periphery (see the image below). Veins: blood flow and valve structure.

Contents: Veins and Arteries There are two types of blood vessels in the circulatory system of the body: arteries that carry oxygenated blood from the heart to various parts of the body and veins that carry blood towards the heart for purification.hey are tiny branches of arteries that lead to capillaries and help maintain the pressure and blood flow in the body. Venous valves prevent blood from flowing in the opposite direction. Connective tissues make up the outermost layer of a vein which is also known as-tunica adventitia or tunica externa.

- Veins are a part of the human cardiovascular system. There job is to return blood back to the heart after the blood has circulated through the body by way of the arteries. The … arteries, which carry the blood away from the heart, eventually divide into small capillaries, or tiny blood vessels, which diffuse oxygen originally from the heart into body cells.

Vein The pulmonary veins carry relatively oxygenated blood from the lungs to the heart. The superior and inferior venae cavae carry relatively deoxygenated blood from the upper and lower systemic circulations, respectively. The portal venous system is a series of veins or venules that directly connect two capillary beds.he arteries are perceived as carrying oxygenated blood to the tissues, while veins carry deoxygenated blood back to the heart. This is true of the systemic circulation, by far the larger of the two circuits of blood in the body, which transports oxygen from the heart to the tissues of the body.

- Pulmonary Vein Function. The basic function of your pulmonary veins mirrors that of other veins in your body: they transport blood back to your heart. However, unlike all of the other veins in your body, which ultimately deliver deoxygenated blood to your heart, the pulmonary veins carry oxygenated blood to your heart. Hence, the principal function of the pulmonary veins is to act as a conduit for oxygenated blood between your lungs and your heart.

Blood Vessels The heart pumps blood throughout the body. Sixty thousand miles of blood vessels transport the blood, enough to encircle Earth more than twice. Arteries carry blood away from the heart; capillaries reach all of the body's seventy trillion cells; and veins carry blood back to the heart. Because blood vessels form a circular route, this system is also called the circulatory system. The cardiovascular system has two main parts.

Cardiovascular System Anatomy Veins and Venules: Veins are the large return vessels of the body and act as the blood return counterparts of arteries. Because the arteries, arterioles, and capillaries absorb most of the force of the heart’s contractions, veins and venules are subjected to very low blood pressures.

How does the circulatory system work? Your heart is the pump for your circulatory system. It is made of muscle and contracts in order to pump blood through your body. The arteries and veins are the roadways through which blood is transported to all parts of your body. Arteries carry oxygen-rich blood from your heart to the rest of your body.Veins return the blood to the heart after the oxygen has been used. Your body needs oxygen in order to function.he arteries and veins are the roadways through which blood is transported to all parts of your body.
